Distribution of the Long non-coding RNAs (LncRNAs) across the Arabidopsis thaliana genome. The positions are named as follow: conservation level_lineage of sequence conservation_gene function. Conservation level can be P: conserved by position across multiple lineages. S: only conserved by sequence and not by position. Ae: conserved by sequence only in Aethionemeae. All: conserved by sequence through Brassicaceae and Aethionemeae. B: conserved by sequence only in Brassicaceae, including Aethionemeae. Cl: conserved by sequence only in Cleomaceae. The numbers left of the chromosome are the distances from the gene to the end of the chromosome in Mega bases
